As shown in Fig. 1, the machine is provided with a keyboard ilvcomprising a plurality of ordinally arranged rows .of keys 3|. After the'if' has' seothe keyboard' 2Q it en? Divided and this application July5,

Registration control mechanism Referring in Figs. 2A and 2D. Associatedwith each ordinal row of keys 2| is a shaft 3Q which in each cycle isrotated a differential amount corresponding to the key 2| depressed.This is effected by the following mechanism. Shaft 30 has a threadedportion 3| on which is threaded a nut 32 having an annular groove 33engaged by a fork 34 on a member 35 mounted for sliding movementparallel to the axis of the shaft 30. The nut 32 is provided about itsouter periphery with a series of teeth 2G which are adapted to cooperatewith a stationary tooth 2l extending longitudinally beneath the shaft353 so as to restrain the nut against rotation while permitting it totravel forwardly and backwardly in the machine. The tooth 2'| is of suchlength as not to engage between the teeth 2 5 when the nut is in itsnormal or rearmost position as shown in Fig. 2A. Hence, the nut 32 andthe shaft 35 are free to rotate when the inter-order transfer mechanismoperates near the end of the cycle. Member 35 has a rack 35 rigidlyattached thereto which engages a gear 4l! having a pinion (Fig. 4) ofsmaller diameter integral therewith engaging a fixed rack 4|. The gearand pinion are mounted for rotation on a stud 42 in a slide A3. Slide c3has two pin and slot connections 4'4 with the member 35, and a spring 45is attached at its front end to a stud 46 on the slide i3 and at itsrear end is attached to the pin il of the rear pin and slot connection44. Pin 4'! is secured to the member 35 so that the spring 4'5 tends tomove the member 35 forwardly, and the slide i3 rearwardly. A latch 59mounted on the pin el normally engages an ear 5| on the slide 53preventing movement of the slide 63 and the member 35.

In the full cycle position all of the members 35 are,

restrained from movement by a bail 52 secured to a shaft 53 whichengages slots 56 in the members 35.

When a numeral key 2| (Fig. 2A) is depressed it releases the latch 5B bythe following means. Each key 2| (Fig. 4) has a lug 55 which engages abail 56 pivoted at 51. As shown in Fig. 2A, the bail 55 is common to allthe keys 2| in the ordinal row so that depression of any key will causerocking of the bail. The bail, when rocked, engages a pin 58 on a slide59. which has a pin S8 that engages the latch l592|. Upon depression ofeithenof the bars 22, 23 (Fig. l) by a means fj presentlyito bedescribed, the bail 52 (Fig. 2A) is p 60 1' cEedounter-clockwise. Anymember t'which has been unlatc'hed'- is" now free tomove forwardlyunderthe influence of its spring (l5. Thel slide 155 will be movedforwardly but, at a slower speed. The member is the driving memberbecause of the mechanical advan-tag'e'it hasin` The shaft 3U to berotated a corresponding" angular amount.

However, during this part of the cycle thev angular rotation of theshaft 39 is not registered. Thevremaind-er of the registration controlmechanism corresponds to that described in the patent'toFride'n2,229,889, issued January 28, 1941;

and'comprises a square shaft 62 rigidly secured.

to the threaded shaft 55. Slidably. mounted onA the square shaft 52 is asleeve 553 having` a pair of bevel gears 55, G5 integral therewith.These gears are normally in a neutral position with respect to a bevelgear 55 (Fig. 2C) onthe numeral wheel shaft 5l' which has Vmounted atthe upper end thereof a numeral wheel 58. All of the` bevel gears 5A. 55are controlled by a gate 'lilsecured to ashaft l! suitably mounted inthe frame of-v the machine. By a means presently to be described, thegatey l@ is rocked clockwise to engage the bevel gears 54 with the gears55 foradditive registration7 and is rocked counterclockwise to engagebevel gears |55 with the bevel gears 55 for negative registration.During the forwardmovement'of the bail 52 (Fig. 2A) the gate l@ is inits neutral position so thaty the angular movement of the shaft 3U isnot transmitted to the numeral wheelz. Atthe end. of the-forwardmovementrof the-bail 52 the gate l@ isV moved to engage either the gearsor the gears 55 with the gears (i6 sothat upon return movement of thebail 52 any differentially displaced members 35 are restored to theirhome position, causing angular rotation of the shaft 3l! correspondingto the value of the numeralwheel depressedwhich is registered in thenumeral wheel Sii. In the last part of the cycle, the bail 52 moves tothe bottom of the slot 54 without causing displacement of the member andthen returnsV to the-starting position shown. During this lastpart ofthe cycle, the shaft l2 is rotated. This shaft is connected by bevelgears '53 to shafts l5, each of which has two transfer teeth 'i5 thereonwhich cooperate with transfer gears 16 on each pair of square shafts 52in the manner described in the aforementioned. patent. As thereexplained, the transfer gears 'i5 are moved into operative relationshipwith their transfer teeth l5 by means of a transfer tooth il (Fig. 1,5)on the numeral wheel shaft (il which rocks transfer levers '|13whenever" the numeral wheel 63 passes from (i to 9 or from 9 to (l. Eachtransfer lever has an ear (see also 2C) which engages a grooved collar5| (Fig. 2B) secured to the' hub of the gear l5. One ange of the collar8! is disposed in a grooved collar 23 on al pin 84 slidably mounted inthe frame. A bail 8 5'mounted on a sleeve 55 rotatably mounted on theshaft di is rocked clockwise in to restore the pins tiand thus gears l5.

Operation control mechanism y lteferring to Figs. 5 and 6. the plus bar22 is secured'to a verticall,T sl-idable key stem 9,5, and the minus bar23 is secured-tov a vertically slidjusting crank |3l.

able key stem 9|. A link 521is'pivoted tothe key stem 955 at 93 and hasa pinarid slot connection @4i with the key stem 5|. Depression of eitherof the keys 22, 23 causes the link |32 to engage a pin S5011 anarm 95secured to a shaft 5l. Shaft Sl is urged clockwise in Fig. 5, orcounter-clockwise in Fig. 10A by a spring 98 attached to an arm 55secured to the shaft Sl. The shaft 9'! (Fig. '7)- has an arm |55provided with a pin IDI which engages a lever |52 pivotally mounted at||i3`and`havingan`ear |25 engaging the plunger |55 of ar micro switch|55. Closure of this switch starts the motor. Shaft 5l (Figs. 8 and 9)has an arm` lill which controls a pawl and ratchet clutch |55 in a wellknown manner. The driving side of this clutch is connected to the motorbythe gear train shown in Fig. 3, and comprises a pinion |09 on themotor shaft and intermediategearing H5, ||2. The driven side of theclutch has attached thereto a gear i iii-meshing with a gear Ml which,through a connecting rod H5 oscillates a crank H5 secured to shaft ShaftIll (Fig. 10A) is connected by an arm H8 to the piston rod I |9 of adash pot |25. The driven side of the clutch is also secured to atransversely extending shaft |2| (Figs. 5 and 6) which, at the rightend, has secured. thereto a cam |22 having a pin |23 thereon to which ispivoted a link |24 which is pivoted to a crank |25 on the shaft 53 sothat for each revolution of the shaft |2| the shaft 52 isoscillated'counter-clockwise from the position shown, and then isreturned clockwise to the full cycle position. The shaft 53 has securedthereto a bail 52 (Fig. 2A) as previously described.

When either of the keys 22, 23 is depressed the.

gate 'l5 (Fig. 2B) is not positioned. This is effected subsequently bypower. Key 22 hasa pin |25 (Fig. 5) which engages acam face |21 on alink |28 element pivotally mounted at its front end on an arm |29,pivotally mounted at |v |35 on a bellcrank |31 secured to the shaft Hv(Fig. 2B) of the gate 10. The slot end |33 and pin |55 provide a lostmotion connection between the element |23 and the sign control ad-Depression of thev key 22 also rocks the link 92 (Fig. 5) around the pinand slot connection 94 and a pin |38 in the link 92 engages the tail |39of a latch lili] rotatably mounted on the shaft 97. The latch whichnormally engages a shoulder |ll| (Fig. 6) on a latch or slide |42,releases the slide for upward moveinent'under the bias influence of aspringto theV upper end of the slide |42. movement of the slide i2disposes the upper end thereof in front of an ear |54 on the link |28 tomaintain the link |28 in its rearwardly displaced position. After thebail 52 (Fig. 2A) has reached the end of its forward stroke a cam |45(Figs. 5 and 6) rocks its follower |55 counter-clockwise on its pivot|67. A link |48 transmits the movement of the follower to a leverrotatably mounted at |5| and connected at |52 to a vertically movableslide |53 having a pin member |55 therein. Pin |54 engages the cam face|55 on the slide |28 and imparts further rearward movement to the link|28, which movement causes cockwise rotation of the shaft '1| to engagethe -bevelgears for'ad-ditive registration', as

previously described. rThe shaft 1| is latched in this position by alatch |55` which cooperates with an ear |51 on the bellcrank |31. Whenthe link |28 is moved rearwardly, a cam face |55 thereon engages a pin|5| on the bellcrank |43, rocking the bellcrank |43 counter-clockwise,moving the slide |42 downwardly where it is relatched by the latch |40.As previously described, the shaft 53 is then rocked clockwise, causingdigitation.

The transfer is timed by a Geneva wheel |52 (Fig. 6) pivoted about ashaft |63 which has secured thereto a gear |54 which, throughintermediate gear |65 (Fig. 5) imparts a complete rotation to pinion |66on shaft 12 (see also Fig. 2A). The Geneva wheel |62 is given aone-third revolution in the latter part of the cycle of the shaft |2| bydriver pins |31 which engage the slots of the Geneva wheel |62.

At the conclusion of the cycle the gate 15 (Fig. 2B) is restored to itsneutral position. A cam |22 (Fig. 6) at the end of its revolutionengages a follower pivoted at |1| which has a pin |12 thereon thatengages the latch |55 and rotates it counter-clockwise to release thebellcrank |31. The shaft 1| is then centralized (see Fig. 10A) by aconventional centralizer mechanism |13. In case the operator does notrelease the key 22 in time for the latch |42 to oe free to re-engage theshoulder |4| on the slide |42 when the latter is moved downwardly by theaction of the cam face |59, the pin ii and the bellcrank |53, the slide|42 will be moved downwardly again near the end of the cycle by theaction of the cam |22 and the cam follower' |151 acting on the slide |42through a pin and slot connection |14-, By this time the key 22 normallywill have been released so as to condition the latch i4@ for reengagingthe slide |42 when the latch is in its lower position.

Minus registration is effected by depressing the key 23 (Fig. 5) whichhas a pin |15 on its key stem which engages a cam face on the link |28and moves the link |28 forwardly to bring the rear face |11 (Fig. 6) ofthe slot |34 into engagement with the pin |35. Depression of the key 23also causes rocking of the' link 92 about its pivot 93 and the pin |38on the link releases the latch |45 which permits the slide |42 to moveupwardly behind the ear |44 on the link 23. By the mechanism previouslydescribed, the cam |45 (Fig. 5) causes the pin |54 to be moveddownwardly into engagement with the cam face |13 on the slide |23positively, rocking the bellcrank |31 counter-clockwise to move the bailshaft 1| to its subtractive position where it is held by the latch |53.The cam face |80 on the link |28 (Fig. 6) engages the pin ll to rock thebellcrank |43 counter-clockwiseas before.

The transfer gears are restored, es previously described, by rocking thebal 85 (Fig. 2B), which is secured to the seeve 35. Referring to Figs.1l and 12, the sleeve 86 has secured thereto a cam follower |82 whichcooperates with the cam |53 secured to one of the actuator shafts 14.

Keyboard lock and release the operation a bail |89 is rockedclockwise'by its shaft |90 to move all of the latch slides |85-rearwardly to clear the keyboard. This is effected as follows. The shaft53 (Figs. 2A andi 14) has secured thereto a cam |92 which has a follower|93 (Fig. 14). The follower |93 is connected by a link |94 whichconnects the follower |93 to a pin |95 on an arm |93 rotatably mountedon a stud |91 in the frame of the machine. A link |98 connects the pin|95 to an arm 200 rotatably mounted on the Shaft |30 as shown in Fig.14. One arm ofthe bail |89 is connected by a link to a bellcrank 202pivotally mounted on the pin |91 and pivoted to a depending por'- tion203 of the lock bail |88. A spring 204 urges bail |89 clockwise andthrough the link 20| urges the lock bail upwardly, it also maintains apin 205 on bellcrank 202 in contact with arm |96. The operation of theseparts s as follows. In the forepartk of the cycle the cam |92 rotatesclockwise and the link |34 is moved forwardly', rocking the arm |95counterclockwise, bellcrank 202 follows, and the lock bail |88 is movedup- A wardly. In the last part of the cycle the cam |92 rotatescounter-clockwise beyond the position shown, moving the arm |95 and thebellcrank 202 clockwise to withdraw the lock bail las and through thelink zal, rock the bail |89 counter-clockwise to release the latchslides |85.

True negative total Each numeral wheel 58 (Fig. l2) has secured theretoa gear 2 I3 meshing with the gear 2 on a shaft 2|2 provided with anumeral wheel 2|3. The numerals on the numeral wheels E8 and 2 |3 arearranged the same, but the wheels rotate in opposite directions at alltimes, and the numeral wheel 2| 3 is adapted to display the complementof the'numeral on the numeral wheel 58; For example', when the wheel 58is standing at 9 the wheel 2 I3 is standing at 0. Normally, the numeralson the numeral wheel |58 are visible through the windows 24 (Fig. 1).When an overdraft occurs, a true negative total is displayed through theupper row of windows'25: Windows 24 and 25 are in a shutter 2|5 (Figs.11. 12 and 13). When an overdraft occurs this shutter is moved to theright in Fig. l to display the numerals on the numeral wheels 2|3 and tomask the numerals on the numeral wheels (58- and a registration of l iseffected in the units order by a mechanism which will now be described.Referring to Fig. 15, the highest order numeral wheel shaft 51 isprovide-d with a transfer tooth 11, which cooperates with a lever 2 |1secured to a shaft 2|8 which has secured thereto an arm 2|9 which -isconnected by a link 22| to an arm 222 secured to a shaft 223 having atransfer lever 224 thereon which is provided with an ear that engages agrooved collar 3| (Fig. 2B) attached to a transfer gear 16 on the squareshaft 62 in the units order, A transfer tooth 15 is provided on thefirst actuator shaft 14 and is timed to engage its pinion 16 aftertransfer has been effected in the highest order so that whenever thehighest order numeral wheel passes through the 9-0 position theregistration 0f"1 is effected in the units order. If the operation isnegative and an overdraft occurs the highest order numeral wheel willpass from 0 to 9 and this will cause subtraction of 1 in the unitsorder. When the overdraft is corrected by an additive operation, thehighest order numeral wheel will move from 9 to '0 and .this Lwill'cause' 11" tolbeadde'dlin he nitsordenf' if; .`.-\S. l'. "I 555i 7,.The'actuator shatM (Fig. 11) has acam 22,5 thereon which,` inthecourseof the transfer phase raises a. follower 225 which has aspring-pressed rod 22'! attached'thereto. Rotatably `mounted-.on the rod221 isa lever 228 which has a pin 229 constantly in engagement with aslot 234i (Fig. 13) in a plateA 232; The follower end of the'rod 22! hassecured thereto an arm 235 provided with a pin 236 which normallyengages in one of two holes-.231. The plate 232 is rigidly attached tothefshutter 2 l'so'that the pin 236' engagingone of the holesl 231'locks the shutter inv its current position. When the cam 225 lifts therod 22.1 it removes the lock pin 235 so that the plate.v 232 and theshutter 215 are free to be adjusted. The front end of the lever 228(Fig. 12) has a pin 240' whichv is brought into engagement with thetoothofa gear 24| on the numeralwheel shaft 2.12 in; thel units' order.This occurs during: a transfer, and` if an overdraft occurs thev unitsorder. numeral wheelv shaft 2l2 will be rotated one placevcounter-clockwise. This is because the reversing gears 64, 65 areVadjusted for subtraction, and when the addeciincrement` is entered invthe units order it will cause the numeral wheel 68. to rotate clockwiseas viewed from above, and, therefore, will rotate the gear 24!counter-clockwise. This movement is transmitted through the pinv 24D,the lever 228 andthe pin 22] to the-plate 232 which is moved. to theright, moving the shutter 2|5 to the right, Fig. 1. At the end of thecycle, the lock pin 236 drops into the hole 237ito hold thek shutter inposition to display the true negative total in the windows 25. When theoverdraftis corrected the numeral wheel 213 will receive an increment ofmovement in the opposite direction, that' is, clockwise, and through themechanism just described, the shutter willv be moved-to the leftih Fig.1 to' again display the tntal'standingin the numeral Wheels 68.

Anl illustrative example of the above described mechanism is givenbelow, in which the numbers standing in the numeral wheels 68 appear inthe left-hand column', and those standing in the numeral wheels 213 arein the right-hand column. IE-lief numerals displayed by the shutter aremarked with anl asterisk. The figure 5369 is registered in the numeralwheels 68, 6,000 is set in the keyboard and is subtracted, this resultsYin an overdraft' and subtraction of l in the units order. It also causesshifting of the shutter so that'the true negative total 631 isdisplayed. The overdraft is then connected by adding 2579 which causesthe highest order numeral wheel 88 to passv from 9 to 0 andl'isadditively registered. in'. the units order; The shutter againshifts', and-the new/total, 1948, is displayed.
